F. G. BROTZ COMBINATION ELASTE CONNECTION Flled Jul 11 1928 WITNESSES AT T RNEY Patented Jan. 28, 1930 UNITED STATES PATENT: OFFICE FRANK G. BROTZ, F KOHLER, WISCONSIN, ASSIGNOR TO KOI-ILER COMPANY, OF KOHLER, WISCONSIN, A G'ORPORATION OF WISCONSIN I COMBINATION WASTE CONNECTION Application filed July 11,

This invention has for its object to provide a combination waste connection for bathtubs and the like constituting a unitary fitting embodying within it all of the essentials for servicing the waste water of the bathtub.

Another object of theinvention is to pro vide such a unitary structure having tight sealing connections with the drain outlet and the overflow opening of the bathtub and having incorporated in it the waste control valve and trap leading therefrom and serving when attached to the bathtub to eliminate the necessity for further plumbing connections for the waste except the sewer and vent connection withthe trap.

Another object of the invention is to adapt the combination device as an attachmentsuitable for ready connection with bathtubs of any manufacture. 1

Another object of the invention is to provide such a combination device, which, when attached, will conform with the usual roughing-in practice by presenting the Waste coupling in the usual central location.

With the above and other objects in View the invention consists in the combination waste connection as herein claimed and all equivalents.

Referring to the accompanying drawings, in which like characters of reference indicate the same parts in different views,

Fig. 1 is a sectional view of the end of a bathtub provided with a combination overflow, drain and trap constructed in accordance with this invention, being sectioned on the line 11 of Fig. 2; a

Fig. 2 is a bottom view thereof;

Fig. 3 is a side View, and

Fig. 4 is a detail view of the overflow.

In these drawings, 10 indicates a bathtub having the usual conically depressed drain outlet 11 and the usual overflow opening 12. The combination waste fixture of this invention is designed to make tight fitting connection with both of these parts and to control and dispose of the water passing through them. With this object in view a valve chamber 13 has an elbow-shaped waste conduit 14 preferably formed integral therewith and i adapted to be sealed with the drain outlet 1928. Serial n' aeuses.

and also has an upwardly extending exteni sion 15, preferably integral therewith, adapted to be sealed around the overflow opening. Around the upturned end of the elbow-like waste conduit 14 is a circular groove containing a lead or rubber gasket 14 fitting against the bottom of the drain outlet 11. Contained within the depression of said drain outlet 11 is an arched spider-like strainer member 16 with the free'ends of its radially extending legs bearing, directly upon the rounded walls of the drain outlet and a screw 17 let into the center of the strainer member threads into a boss 18 in the bottom of the-elbow of waste conduit 14 to clamp-the latter in its seating engagement with the drain outlet and to attach the combination waste device to the tub. 2 The upper end of the extension 15 of th valve chamber terminates in a circular throat i having a gasket 19 and a cross-piece 20 forming a bridge across it. Inside of the tub is an escutc heon-plate 21 arched at its central part to form a slotted hood with downwardly turned entrance opening. Screws 22 are countersunk in theescutcheon-plate and are threaded in the bridge 20 to clamp these parts together and seal the waste attachment to the tub around the overflow opening. i

Where the Waste conduit 14 joins with the valve chamber 13 it terminates in a conical seat 23, against which fits the conical end of a projection 24 on a cover-plate 25' which is secured to the valve chamber by screws 26 to form a water-tight closure for a hand hole I in the valve chamber. The projection 24 has a recess 27 forminganextension of and communicating with the waste conduit 14, and a vertical opening 28 through the projection 24 forms a guide and valve seat for a valve member 29 to control communication between the waste conduit and the valve chamber through said recess 27 and opening 28.

The valve is operated by means of a stem 30 having a bearing in cross-piece 20 and in the hooded portion ofthe escutcheon-plate 21 with a handle 31 on one end and a crank 32 on the other, which latter is connected by arod 33 passing down through the valve chamber extension 15 with the valve 29. The rod 33 is bent to follow the angular course of the extension 15 of the valve chamber because the valve is offset to one side of the center line of the tub, which passes through the over- 5 flow opening.

Formed integral with the valve chamber and in said center line is a water trap 34 having overlapping upper and lower partitions separating it from the interior of the valve chamber to form a water seal and leading from said water trap in the center line is a waste coupling elbow 35 and a vent pipe 36 for connection with a sewer and the vent re spectively. A screw plug 37 in the end of the trap affords an alternative location for the waste coupling 35.

The water trap maintains a water level in the valve chamber and the waste conduit. as shown. \Vhen the valve is lifted off of its 1 seat by turning the handle 31 the tub is drained, but when said valve is closed there is no communication between the waste conduit and the valve chamber, thus closing the waste discharge from the tub except through the overflow. The waste attachment of this invention may be attached to any bathtub and will serve to minimize the plumbing connections necessary for installation and at the same time the valve and valve seat are made "80 accessible for cleaning or repair, it being only necessary to remove the cover-plate and unhook the valve from the rod 33 for this purpose. By reason of the angular relation of v the parts, as shown in Fig. 2, the waste con- 35 pling 35 may be retained in the central position to conform with roughing-in practice.

\Vhat I claim as new and desire to secure by Leters Patent is:

1. A combination integral overflow, drain and trap unit fixture, comprising a valve chamber, a waste conduit leading thereto, clamping means for fitting the waste conduit to the drain outlet of a bathtub, a valve controllin communication between the waste 1 6 COIldllli-ulld the valve chamber, a cover-plate for a hand hole of the valve chamber having a projection forming the valve seat of said valve on the valve chamber, clamping means for fitting the upper end of the valve chamber extension to the overflow opening of the bathtub, and a trap through which the water in the valve chamber is discharged.

2. A combination integral waste attachment comprising a valve chamber, awaste conduit leading thercto and terminating in a conical seat, clamping means for connecting the waste conduit to the drain outlet of a bathtub, a cover-plate for a hand hole of the valve chamber having a projection with a. conical end seated on the conical seat, a valve in the projection controlling a passageway through the projection connecting the waste conduit with the valve chamber, an extension of the valve chamber adapted to be fitted to the overflow opening of the tub, and operating means in said extension connected with the valve.
